FIRE-EXTINGUISHER BRACKET.

Specification of Letters Patent.

Patented Aug. 26, 1919.

Application filed March 26, 1919. Serial No. 285,272.

To all whom it may concern:

Be it known that I, BENJAMIN DoRs'rRoM, a citizen of the United States,residing at Bristol, in the county' of Bristol and State of RhodeIsland, have invented a new and useful Improvement in Fire-ExtinguisherBrackets, of which the following is a specification.

This invention relates to certain new and useful improvements in a fireextinguisher bracket specially adapted for the well known type ofportable chemical fire extinguisher containing an acid for mixture withan alkali solution upon turning the .device upside down.

The principal object of this invention is to provide a bracket whichwill automatically invert its supported extinguisher in the event offire and thereby cause the contents to be sprayed out through thedischarge nozzle and extinguish the fire within its reach.

' A further object of this invention is to provide a bracket normallyheld upright by a fusible member and adapted to move to invertedposition upon the melting of the fusible member whereby the chemicalcontents of a supported fire extinguisher will be caused to commingleand discharge through the discharge nozzle to the surrounding area.

The invention further resides in the features of construction and thearrangements and combinations of parts hereinafter described andclaimed, reference being had to the accompanying drawing depicting thepreferred form of the invention and wherein- Figure 1 is a sideelevation of the improved bracket with parts in section and showing afire extinguisher supported thereby in normally inoperative position,and

Fig. 2 is a front elevation of the bracket per se.

The bracket construction is adapted to be attached to the side wall of abuilding or room and includes a wall-attaching support 1 having its endsformed to receive attaching screws 2, the upper end being also formedwith a cylindrical socket 3 opened at its inner end and closed at itsouter end except for a small central opening through which a stem 4slides. This stem or pin carries a plunger or head 5 on its inner endfor sliding fit with the interior of the cylindrical socket and has itsouter end formed with a transverse opening to receive a fusible pin 6, aspring 7 being coiled around the stem and compressed between the head 5and the closed end of the socket for exerting an inward force tending todraw in the stem.

The fire extinguisher support comprises an L-shaped frame whose verticalarm v8 is provided intermediate its ends with a rearwardly extending hub9 and ivot pin 10 which latter is journaled in a caring provided in thewall-attaching support and secured against displacement by the cotterpin 11. A coiled spring 12 encircles the hub 9 and has its terminalsengaged with the arm 8 and supp lort 1, respectively, to supply a torquesu cient to rotate the L-shaped frame one-half revolution. The base 13,of the frame is dished to receive the lower end of the extinguisher 14:,and carried on the upper portion of the vertical arm 8 is a circularspring clamp 15 opening outwardly to permit the insertion of theextinguisher. The clamp is designed to snugly embrace the upper endportion of the extinguisher about its bead 16, bein formed with a grooveto receive said bea and thereby hold the extinguisher down in its seatin the base.

In practice, the spring-retracted stem or pin 4 is pulled out and passedthrough a perforation in the extreme upper end of the arm 8 where it isheld by the fusible pin (3 serving in the capacity of a cotter pin. Theextinguisher is placed in the base 13 and between the clamping arms 15.Upon the occurrence of a conflagration in the vicinity of the bracket,the heat will melt the fusible pin and consequently the spring retractedpin will be free to withdraw from the aperture in arm 8 to release theframe for the rotative action imparted thereto by the coiled spring 12.Upon being inverted the weight of the extinguisher is transferred to thespring clamp 15 and the acid contents of the receptacle are caused tocommingle with the alkali for effecting a discharge of the liquidthrough the rubber hose 17 and the attached nozzle 18.

Provision is made for directing the discharging fluid upwardly, byhaving the base 13 formed with an extension 19 of hollow formation, theinterior of said extension being lined with a rubber gasket 20 and thebottom wall perforated to provide a rose 21. The nozzle 18 is forcedinto the hollow extension and firmly held therein by the rubber gasket.Consequently, when the bracket invertsthe extinguisher the contents ofthe latter will be expelled through the rose 21 Which spreads thequenching liquid in an ef-' ficient manner.

The bracket operates automatically upon the occurrence of a fire Withinits vicinity where sufiicient heat surrounds the fusible pin to melt it,and when the extinguisher is put into operation the contents aredirected upwardly so that should the fire be located beneath the samethe liquid will fall to the floor and thus serve to extinguish theflame.

Having thus described my invention, what I claim as new and desire tosecure byLetters Patent is V, V

1. A bracket for supporting and automatically putting int-o operation afireextinguisher, comprising a wall-attaching sup port adapted to besecured at its ends to a wall and formed at itsupper end with acylindrical socket closed at its outer end, a spring retracted pinoperable inthe socket and projecting through its closed end, said outerend of thepin havinga transverse opening therethrough, a frame includinga vertical arm provided with a pivot pin projected rearwardly therefrombetween its ends and 'journaled in a bearing provided in the support, anextinguisher vsupporting base secured at the lower end of theja'rm,'anextinguisher. embracing springclamp carried by the upper end of the arm,said arm having a perforation in which the spring retracted pin isengageable, means for turning the frame on its pivot when said springretracted pin is withdrawn from the arm aperture and a fusible membernormally holding the pin engaged in the arm aperture.

2. A fire extinguisher bracket comprising a wall support, a framepivoted thereon and consisting of a dished base to receive a fireextinguisher, means for holding the latter .on the base, means forturning the frame on its pivot, fusible means restraining the secondmeans, and means for holding the nozzle of the extinguisher to directthe discharge of the quenching liquid.

3. A fire extinguisher bracket comprising a support, a frame rotatablethereonand consisting of an extinguisher supporting base formed with ahollow extension on'one side having a perforated bottom, and a rub bergasket liningthe hollow extension and acting tohold the nozzle of theextinguisher therein. V

.4. A fire extinguisher bracket including, an invertible framehaving anextinguishersupporting base, and means carried by the 3 base for holdingthe nozzle of the extin guisher and spraying the issuing jet there:from.

5. A fire extinguisher-bracket comprising an lnvertlble frame cons1st1ngof a base hava l inga hollow extension formed with a perforated bottomto spray the quenching liquid when forced therethrough, means forholding an extinguisheron the base, means for holding the nozzle of theextinguisher in: the hollow extension, and means for an tomaticallyinverting the frame.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
